A'rrAoHMEn'r roe cmimoa T anama-Ina "27, 192 1.. se almfesasaaif tal feature in beet cultivation as at present conducted, is elfectively eliminated and the To all-whow'tit may] concern? Y Be it known that L'NnLLo-Cmm; a subject of King Victor Emanuel III of Italy, but having declared my intention to become a citizen of the United States of America, residingat Neldon'a, in the cotmty of Morgan-and State of Colorado, have invented certain new and useful Improvements in At tachments for Beet Cultivators, of which the following is a specification.

' This invention relates to beet cultivators,

and its primary object is to provide an at tachment for implements of the type used in loosening the soil at opposite sides of beet rows, which simultaneously breaks the I crusted ground over the rows before the plants have grown above the surface.

In the culture of sugar beets the productionof a large and satisfactory crop is mainly dependent on thorough cultivation of the soilbefore and after the plants have grown above the surface. It is'customary to use for this purpose an implement equipped with sharesor knives of different forms which cut through the ground at opposite sides of the rows of beets to loosen the soil and destroy the weeds.

A considerable width of ground immedi ately above thebeets remainsuntouched during this operation with the result that be fore the beet plants break through the ground a thick and hardened crust is formed which prevents the penetrationof air and moisture and therebyretards; and stunts the growth of the beets.

By the use of my invention this detrimenentire surface of the soil of a seeded field is constantly maintained in a thoroughly loosened condition to permit of the free passage of air and moisture to the growing plants. v

An embodiment of my invention has been shown in the accompanying drawings in the several views of which like parts are similarly designated, and in whichv Figure 1 represents a side elevation of a beet-cultivator of conventional construction to which my invention is applied.

Figure 2, a plan view of a portion of the tool bar of the cultivator with a pair of cutting tools and my attachment, drawn to an enlarged scale, and

Figure 3, a sectional front elevation of ting members of the"implement are attached .b'yflmeans' of suitably constructed clamps 5. The cutting members are arranged in pairs 'tocut the soilatopposite sides of the beet being apparentthat, my invention is well' -Re'ferring more specifically to the draw-r 1ngs, the reference character 2 designates a ridingicultivator including in connection w1th'a wl1eel supported frame 3, ahorizontall extending tool ham to which the cutrows and they may be made in any of the" several forms adapted for the purpose.

The cutting members 6 shown in the drawvex disks which are convergently arranged ings are made in the form of concavo-conin pairs on the tool bar of the machine, it 7 adapted for use in connection with cultivating tools of this-particular type.

with disk-shaped cultivator tools, since under different circumstances itmay be effectivelye'mployed in association with culti- I desire it understo0d,how ever,' that I 'do' .notl mit my invention for use in connection 'vating tools of different form, principal among whichare the duck-foot,- bull tongue, shovel and knife shape blades. I

My invention consists of-a hub? rigidly fastened upon an axle 8 the ends of which are-rotatably mounted in" axially ali-ned I v v openings of. a forked yoke 9 formed at an end of an arm 10 which is adapted to be at g tached to the tool bar of thecultivating machine by a clamp similar to that employed in l fastening the cuttingtools. I g i The bifurcated end portion of the arm is formed at right angles to its body part which in practice extends horizontally from the tool bar and the opposite end portion 12 of the same is bent upwardly at right angles to the body part for the connection of the 55 clamp. a Y The part 12 of the arm is notched to adjust the depth to which the breaking element enters the ground in the operation of'the element and, the hub '7 is studded with a number of radially pro ecting slender teeth or'spikes 13 which at their innerends are driven into bores at the circumferential surface of the same.

i The attachment is arranged relative to the r 5 pair of cultivator tools with which it is asso- Giltfid to extend rearward thereof with relation to the direction of the operative move ment of the implement and crosswise of the space between them. i

l Vhe'n in'cultivating a beet field the machine is drawn along the rows of beets with the cultivating blades of each pair in cutting engagement with the soil at opposite sides thereof, the teeth of my attachment will break the soil above the beets sufliciently to permit of the penetration of air and moisture but not deep or hard enough to injure the plants.

Having thus described my invention what I claim and desire to secure by Lett ers-Patent is: r

1. The combination with a beet cultivator having a transverse tool bar and a pair of cutting tools thereon, of an arm fixed on said bar to extend im'inovably rearwardly between sald tools, and a rotary ground breaking element on sald arm, adapted to work the ground in a strip including the adapted for rigid connection with said tool 7 bar and the other of which is formed into a forked yoke, and a hub rotatably mounted in said yoke and having outwardly projecting spikes' In testimony whereof I have affixed my signature. j
